Recent Progress on Natural α-glucosidase Inhibitors Derived from the Plants and Microorganisms.

α-Glucosidase inhibitors (AGIs) showcase versatile biochemical activities with respect to antidiabetic, anticancerous, antiobese and antiviral effects. They have drawn a great deal of attention from the scientific community. While α-glucosidase inhibitors are mostly discovered from plants and microorganisms, the recent advance in natural αglucosidase inhibitors over the past five years has been reviewed in this article, and 139 distinct α-glucosidase inhibitors from the plants and microorganisms were classified into ten groups based on their chemical structures, including flavonoids (34), xanthones (6), alkaloids (8), benzopyrones / benzofuranones (8), terpenes (23), saponins (8), phenols / alcohols (25), esters (18), chalcone (5) and other compounds (4).

A combined upflow anaerobic sludge bed, aerobic, and anoxic fixed-bed reactor system for removing tetramethylammonium hydroxide and nitrogen from light-emitting diode wastewater.

A laboratory study using a combined upflow anaerobic sludge bed (UASB) and aerobic and anoxic fixed-bed reactor system was undertaken to explore its capability for removing tetramethylammonium hydroxide (TMAH) and nitrogen from light-emitting diode wastewater. When the organic loading rate was maintained at 0.26-0.

Removal of nitrogen from secondary effluent of a petrochemical industrial park by a hybrid biofilm-carrier reactor with one-stage ANAMMOX.

A laboratory study was undertaken to explore the capability of one-stage ANAMMOX in a hybrid biofilm-carrier reactor (HBCR) fed with petrochemical wastewater. Under favorable operating conditions in continuous-flow operations (at the dissolved oxygen level of 0.5-1.
